Getting "Please match the requested format" with Firefox
I can configure IPv6 using SLAAC, but when I try to use a static address I get the "Please match the requested format" error. I've seen others report this as a Chrome bug, but I'm using Firefox 49.0.1 on Windows.
pfSense is 2.3.2-RELEASE-p1 (amd64).
See attached screenshot. I can't see any reason why the IPv6 address is incorrect. I've allocated similar static addresses to other devices without any issues.
Use lower case letters, not upper case.
Thanks. Using lower case for the alphabetic hex characters in the interface address works.
It's a bit inconsistent though, as the interface allows upper-case characters when adding the IPv6 gateway.
